From January 1976 to November 1978, 2592 nonstress tests were performed at the authors' institution on 862 fetuses, of which 2239 (86.3%) had reactive and 353 (13.6%) had nonreactive results. Of these 862 fetuses, 842 were delivered at the authors' hospital. Of these 842 fetuses, 109 were delivered within 1 week of a nonreactive tracing and 733 were delivered within 1 week of a reactive tracing. A retrospective analysis was performed on 102 of the nonreative tracings done within 1 week of delivery to assess the significance of various components of the nonstress test on the subsequent stress test and perinatal outcome. No significant difference could be observed in the number of fetal movements and total number of accelerations as compared with the subsequent stress test. However, the nonreactive tracings of the contraction stress test (CST)-positive group differed from those of the CST-negative groups in number of accelerations over 15 beats per minute (38% versus 48%) (P < .05) and in the number of accelerations lasting longer than 20 seconds (20% versus 50%) (P < .01). The number of nonreactive fetal movements per test (2.6 versus 0.96) (P < .05) and the percentage of nonreactive fetal movements (33% versus 15%) (P < .01) were different in both groups. The growth-retarded fetus in the nonreactive group did not differ in the number of fetal movements or total accelertions when compared to fetuses born appropriate for gestational age, but the number of accelerations was more than 15 beats per minute (26% versus 50%) (P < .01) and the number of accelerations lasting 20 seconds (11% versus 28%) (P < .01) did differ significantly.
1976年1月至1978年11月期间，作者所在机构对862例胎儿进行了2592次无应激试验，其中2239例（86.3%）结果为反应型，353例（13.6%）结果为无反应型。在这862例胎儿中，842例在作者所在医院分娩。在这842例胎儿中，109例在无反应型描记图后1周内分娩，733例在反应型描记图后1周内分娩。对分娩前1周内进行的102例无反应型描记图进行回顾性分析，以评估无应激试验各组成部分对随后的应激试验及围产期结局的意义。与随后的应激试验相比，胎儿运动次数和加速总数未观察到显著差异。然而，宫缩应激试验（CST）阳性组的无反应型描记图与CST阴性组的无反应型描记图在每分钟超过15次心跳的加速次数（38%对48%）（P<.05）以及持续超过20秒的加速次数（20%对50%）（P<.01）方面存在差异。两组每次试验的无反应型胎儿运动次数（2.6对0.96）（P<.05）和无反应型胎儿运动百分比（33%对15%）（P<.01）也不同。无反应型组中生长受限胎儿与适于胎龄出生的胎儿相比，胎儿运动次数或总加速次数无差异，但每分钟超过15次心跳的加速次数（26%对50%）（P<.01）以及持续20秒的加速次数（11%对28%）（P<.01）确实存在显著差异。
